摘要
基于调频广播的无源定位系统由于具有隐蔽性好,反隐身等特点,一直受到人们的关注。文章主要基于调频广播信号的特征,以及无源定位系统直达波功率远大于目标回波功率这一特性,对接收机展开研究。分析了适用于基于调频广播的无源定位系统的信道化射频数字接收机的主要特点。
The passive location system based on FM broadcast signals has been paid attention to by people because of its good invisibility, anti stealth and so on. This paper mainly based on the characteristics of FM broadcast signals, as well as the direct wave power of the passive location system is much larger than that of the target echo power. The main features of the channel radio frequency digital receiver which is suitable for passive location system based on FM broadcast is analyzed.
